加强建设项目环境保护管理工作

根据北京市环境状况公告的统计数据,2003年,全市国内生产总值为3663.1亿元,总人口达到1456.4万人,能源总消耗4707.5万tce.同时,能源需求不断增加,机动车数量快速增长,水资源持续短缺,给首都环境质量和生态改善工作带来较大压力.北京现在已经是一个大工地,近几年每年施工建设的开复工面积均在1亿m2左右,背后包含着若干个大大小小的建设项目.如何处理好建设项目在实施过程中与环境保护的关系,值得我们认真思考、总结.

Enhancement of Thermo-Flow Performances by Windbreakers for Two-Tower Indirect Dry Cooling System

The winds will greatly weaken the cooling performance of indirect dry cooling system with twin towers.The exterior windbreakers are recommended to restrain the wind adverse effects in this paper.The macro heat exchanger model was adopted to simulate the heat exchange between circulating water and ambient air.The performances of natural draft dry cooling system(NDDCS)with and without exterior windbreakers were numerically studied.The pressure,velocity and temperature distribution of cooling air in wind angles of 0°,45°and 90°was obtained and presented.The results show that in all wind directions,the performances for lateral sector of towers with windbreakers are significantly improved,but the low-pressure zone appears unexpectedly for the rear sectors,which reduces the air flow rate.The cooling performances of the twin towers with or without windbreakers decrease at first but then recover with the wind velocity increasing.Besides,the optimal flow and heat transfer performances appear in the wind angle of 0°.The cooling performances can be significantly improved in all three wind directions due to windbreaker configuration.     

Investigation of Heat Transfer Augmentation between the Ribbed Plates via Taguchi Approach and Computational Fluid Dynamics

Heat transfer and turbulent flow characteristics between the ribbed plates have been numerically studied in the present paper.The ribs with the rectangular cross-section have been placed on the top and the bottom plates of the duct,symmetrically.It is assumed that the fluid at 300 K has entered the system while the walls kept at 400 K.All numerical analyses have been performed by k-ωShear Stress Transport(SST)turbulence model for Re=10000,15000 and 20000.For the fixed rib width,the dimensionless height and the dimensionless spacing have been respectively varied as 0.1≤h’≤0.3 and 0.5≤S’≤1,and the results have been compared with the ones of the smooth plate.Even though there are twenty-seven cases obtained as a result of parametric combinations,the number of various cases has been reduced from twenty-seven to only nine different variations by applying the Taguchi method.Furthermore,the effects of all the considered parameters on the heat transfer and flow characteristics have been determined in terms of the influence degree.The optimum parameters for Nusselt number and pressure loss have been ascertained individually.What is more,the almost exact values for Nusselt number and pressure loss have also been attained by the confirmation test having an error percentage of 6%.The most dominant factor has been determined as the rib height due to its effect on both heat transfer and flow characteristics.Similarly,with respect to the numerical results,increasing the rib height,the rib spacing and Reynolds number has separately increased Nusselt number.Nevertheless,symmetrical flow structure has been disturbed as a result of ascending the rib height as clearly seen for h’=0.3 from the charts.In the meantime,pressure loss has been augmented owing to the increment of the geometrical parameters and also Reynolds number.h’=0.1 with S’=0.5 at Re=10000,h’=0.2 with S’=0.5 at Re=15000 and h’=0.1 with S’=0.75 at Re=15000 can be suggested for the heat transfer enhancement since the pressure loss of the system is tolerated.     

Experimental Study on Jet Impingement Boiling Heat Transfer in Brass Beads Packed Porous Layer

Jet impingement boiling has been widely used in industrial facilities as its higher heat transfer coefficient(HTC)and critical heat flux(CHF)can be achieved in comparison with the pool boiling.By covering beads packed porous layer on the heated wall surface,the enlarged heat transfer area and rise of nucleation sites for boiling occur,thus,the heat transfer performance of boiling can be enhanced.For the jet impingement boiling with brass bead packed porous layers,the heat transfer performance is crucially influenced by the characteristics of porous layer and working fluid flow,so the experiments were conducted to investigate the effects of the jet flow rate,fluid inlet subcooling,number of porous layer and brass bead diameter of porous layer.Comparison study shows that impingement boiling promotes the HTC and CHF as 1.5 times and 2.5 times respectively as pool boiling at similar conditions.Higher heat transfer performance can be obtained in the cases of a higher jet flow rate and a higher fluid inlet subcooling,and there exist the optimal layer number and bead diameter for heat transfer.Particularly,a double-layer porous layer results in an increase of 39%in heat flux at superheat of 30 K compared with a single-layer case;a single porous layer at d=8 mm brings an increase of 23%in heat flux at superheat of 30 K compared with that of bare plain surface.Besides,the actual scene of jet impingement boiling was recorded with a camera to investigate the behavior evolution of vapor bubbles which is highly correlated to the heat transfer process.     

Numerical Simulation of Dual-Phase-Lag Model and Inverse Fractional Single-Phase-Lag Problem for the Non-Fourier Heat Conduction in a Straight Fin

In recent years,many studies have been done on heat transfer in the fin under unsteady boundary conditions using Fourier and non-Fourier models.In this paper,unsteady non-Fourier heat transfer in a straight fin having an internal heat source under periodic temperature at the base was investigated by solving numerically Dual-Phase-Lag and Fractional Single-Phase-Lag models.In this way,the governing equations of these models were presented for heat conduction analysis in the fin,and their results of the temperature distribution were validated using the theoretical results of Single and Dual-Phase-Lag models.After that,for the first time the order of fractional derivation and heat flux relaxation time of the fractional model were obtained for the straight fin problem under periodic temperature at the base using Levenberg-Marquardt parameter estimation method.To solve the inverse fractional heat conduction problem,the numerical results of Dual-Phase-Lag model were used as the inputs.The results obtained from Fractional Single-Phase-Lag model could predict the fin temperature distribution at unsteady boundary condition at the base as well as the Dual-Phase-Lag model could.

三种干旱指标在北京地区的应用对比研究

基于北京地区的气象资料,比较分析了月尺度、季尺度、年尺度的标准化降水指数(SPI)、降水成数(Deciles)、干旱侦测指数(RDIst),采用1958～2008年的气象资料研究了三者的相关关系,并分析了其在北京地区1999～2007年连旱期间的应用效果。结果表明,SPI和RDIst的相关关系较好,RDIst考虑了蒸发因素对干旱的作用,对实际情况的反映最好,且计算结果稳定,略优于在我国使用广泛的SPI指标。Deciles对降水的敏感度高,月尺度和季尺度的Deciles指标不适于在北京地区应用,而年尺度的Deciles则最能反映干旱过程在历史系列的严重程度。
